As Arthur wrote, you probably do not want to have [[maybe_unused]] active for SOME_PLATFORM, too.   Of course you could also #ifdef the maybe_unused attribute in this specific example as an alternative solution, which arguably would not make it more readable.   -----Ursprüngliche Nachricht----- Von:Giuseppe D‘Angelo via Std-Proposals <std-proposals_at_[hidden]> Gesendet:Do 12.10.2023 15:48 Betreff:Re: [std-proposals] Attribute [[discard]] and attributes on expressions Anlage:untitled An:std-proposals_at_[hidden]; CC:Giuseppe D‘Angelo <giuseppe.dangelo_at_[hidden]>; On 12/10/2023 15:12, Sebastian Wittmeier via Std-Proposals wrote: > template <typename...

[[maybe_unused]] is already doing the right thing, just put it on `foo`'s arguments? -- Giuseppe D'Angelo -- Std-Proposals mailing list Std-Proposals_at_[hidden] https://lists.isocpp.org/mailman/listinfo.cgi/std-proposals
